Flow description
Purpose and benefits
This workflow is designed to automate the process of generating concise and engaging captions for images. It streamlines the task of taking images uploaded by users, analyzing them, and providing a short, catchy caption using artificial intelligence. This can be especially useful for scaling social media content, automating content creation for e-commerce product listings, or any scenario where image captioning is needed at scale.
How the Workflow Operates
Step-by-Step Process
User Engagement and Welcome Message
- When a user opens the chat, a “Welcome to the Image Caption Generator!” message is displayed. This serves to orient the user and prompt them to upload an image for captioning.
User Input Handling
- The user is prompted to upload an image via a chat interface. The system captures both text and file inputs (images) supplied by the user.
Prompt Construction
- A prompt template is used to instruct the AI model: “write a caption for this image”. This template ensures that the AI understands the task is to generate a relevant caption for the provided image.
AI Caption Generation
- The uploaded image, along with the constructed prompt, is fed into a generator node. The generator is configured with a system message to ensure captions are no longer than 5 words and are returned in the format:
Caption: [generated title].
- The uploaded image, along with the constructed prompt, is fed into a generator node. The generator is configured with a system message to ensure captions are no longer than 5 words and are returned in the format:
Output Delivery
- The generated caption is displayed back to the user in the chat, alongside the uploaded image, ensuring a seamless user experience.
Workflow Structure
Below is a summary table of the main nodes and their roles:
| Node Type | Role |
|---|---|
| ChatOpenedTrigger | Detects chat start, triggers welcome message |
| MessageWidget | Displays welcome/instructional message |
| ChatInput | Captures user image upload and text input |
| PromptTemplate | Provides standardized prompt for the AI model |
| Generator | Generates caption using AI, enforces length/format |
| ChatOutput | Shows the generated caption and image to the user |
